I know of one couple who moved back because they could not make their rental feel like home. Rentals can be either damp or cold in the winter and too hot in summer.
Cypriot furniture and particularly rental stuff can be a bit basic and you miss all your own bits. Shipping to Cyprus £3~4K for a 20ft container - storage in UK, no idea but not cheap.
Fact is lots of people don't settle down here and go back - so its a real no right answer question. However there are lots and lots of rentals everywhere and Cypriots ask me every hay if I know of a nice English family who want a villa.
Good luck
Ps See "want to be a Hill Billy" thread by Pete. Never a dull day if you rent up here. Its not true about the wild goings on up here every night - honest its weekends only!
Pps While typing this another thread has come in from Woffie that rather confirms the point.
